Cherry: there is no waveshine. Jump and immediately shine, that's as good as it gets.
Xyro: i have no clue sorry i always play on port 3.
Ozz: 1. always Uair. (experiment with Dair actually... from watching videos vertically is does seem to have quite an influence on momentum)
2. IMO i don't even know why people SHL, SHDL is easier to time and theres another laser. Answering your question there is never a bad time to use SHTL, if you're fluent with it you should only use it, personally i only ever use SHL when im screwing around and feel like looking cool, other than that it's usually SHTL no matter what the character... For me the character only changes how much i laser, not what type i use.
3. Invincibility frames are practically useless, every once and a while you might get lucky and they'll save you but that's probably 1 in 1000. Shine is simply good for mixing it up. Stalling, using it after jab, GTFO move, mindgames... it's usable in practically any situation.
4. not sure, ask Uzi.
5. I think a Fsmash perfectly timed and in the right position clanks with it... just space and try to attack the top you'll have more success than trying to block it with a ground move
